Late on Saturday night, 31 October officers attended an address in Whitgift Street, SE1 to close an illegal rave.
When officers arrived, they were confronted by a large group of people outside the venue.
During this confrontation a number of missiles where thrown at officers, including one reported ‘petrol bomb’.
Fortunately no officers were seriously injured, but four are understood to have been treated for injuries at the scene.
As well as attacking police the group also caused criminal damage to private vehicles and property in the area.
There have been a number of arrests so far (no further details at this time).
A large number of officers, supported by the other emergency services, are still in the area dealing with the ongoing situation.
Any witnesses or anyone with any information about the disorder can contact police via 101 or contact Crimestoppers anonymously on 0800 555 111 or via crimestoppers-uk.org.
